The clados library and associated calculator are ready for use at the beta level. If you care to learn how Clifford algebras (Geometric algebras) work, take a peek. The calculator runs straight from the clados.jar library and the API documentation is available for developers.
The Calculator's user guide is done and in the file release system. There is a bit more debugging to do before the calculator can be released, but it will be done within the next few days.
The viewing utility is mostly together now. After I hook up a few more operations and write a user's guide, it will be time to get back to work on the math.
All this stuff is in English. Sorry I don't know any other languages. If you like translation work and want to help, please jump in.
Work is underway on a viewing utility that should enable users to see how things work behind the scenes.
I am flagging this code as stable. It has been a long time since it has given me any grief in other projects it supports. It is not the prettiest code around and will be refined and expanded latter. For now, though, it works and shows how it works well enough.
